    • 本實驗利用電泳沉積法(electrophoretic deposition; EPD)在不鏽鋼網上沉積多壁奈米碳管，製備海水電池之陰極。將陽極鎂合金與陰極複合電極組裝成海水電池，對其進行材料分析與電化學實驗來評估其海水電池之效益。
    實驗證實，多壁奈米碳管的沉積能有效地降低陰極之內電阻及電荷轉移之阻力，使海水電池之電壓輸出穩定，電流表現也較好。此外，在進行放電的同時，也不會排放出會汙染環境的物質。
     

    In this experiment, multi-walled carbon nanotubes (MWCNTs) are coated onto stainless steel mesh by electrophoretic deposition and assemble a seawater battery cell with magnesium/aluminum alloy as anode and MWCNTs/stainless steel composite as cathode. We find that MWCNT coating reduces internal resistance and facilitates charge transfer at electrode/electrolyte interfaces, allowing seawater batteries to yield higher current and stable voltage output. Meanwhile, no pollutants are released into seawater while discharging.
